@me18: "This clamshell iBook was left off its charger for a week or so (while
running, oops), and now the battery appears undead. It was working fine
before, giving over an hour of use, but I presume it discharged right
down to a point where the electronics monitoring the charge gave up.
It's not entirely dead (ie the battery doesn't show up with an X in the
icon) but it just stays at 0% charge perpetually. If I download Battery
Health Monitor (other ons I have found seem to need 10.4 which this
doesn't have) it just tells me 'unable to read battery status'.
I thought Googling might help (I'm sure I read something before about
'resetting' a battery?) but no luck. I've reset the PMU and the PRAM but
it still sits there at 0%.
For such an ancient (and admittedly battered) machine, it hardly seems
worth spending forty quid on a new battery [1] but as it was to be
passed on to someone who was a) new to computers and b) very excited at
the prospect, it seems a shame to disappoint them. I'd spent ages
setting it all up in numpty mode as well...

[1] I originally thought that would be more than buying an entire
clamshell on eBay, but I was surprised to see that they are still
fetching up to a hundred quid!

Well, a quick browse around at Apple Support finds not much more really,
Apple suggests resetting the PMU, as you've already done. Check the AC
adapter as well, they can also fail.
Apart from that, everything points to a knackered battery. The battery
reset software that was available, was just an update on older books,
and actually around at the time of OS 8.1. The article says that it
isn't necessary on iBooks, as they have the later management software
built in.
